A framework for objective structural frame selection

The choice of structural frame is fundamental to both the short- and long-term performance of a building. An objective and systematic selection process for facilitating the transparent consideration of decision criteria has, however, yet to be developed. This paper reports on the development of a framework that incorporates both ‘soft’ and ‘hard’ performance measures for selecting an appropriate structural frame. The framework requires a systematic evaluation of the importance of each criterion and the likely performance achieved by using various structural frame options. A worked example is provided to demonstrate how project teams can use this framework during the frame decision-making process. To investigate its practical utility, the framework was then tested within two case study projects. The participating engineers responded positively towards the use of multi-criteria for structural frame selection and expressed the view that the proposed framework fosters objective decision making. It is argued that the framework could lead to project teams making more transparent and appropriate frame selection in the future.
